Embodiment 1
[0023] Embodiment 1: see figure 1 , the present invention uses high-quality H-ZPK5 optical glass as the base material, and has made significant progress and breakthroughs in the preparation of secondary molding materials and molding technology. products, and form a pressing technology with core independent intellectual property rights.
[0024] A secondary molding process of fluorophosphate optical molding glass, the method steps are as follows,
[0025] Step 1: machine-cut the raw materials into strips, and thermally cut them into square blocks by adopting a hot-cutting process;
[0026] Prepare materials, before cutting the raw materials, use Solidworks 3D software to draw, calculate the product volume and determine the product weight according to the specific product size, this method improves the accuracy of product volume calculation. According to the relevant technical parameters above, calculate the thickness specifications of the raw materials, and determine the leng...

The invention discloses a secondary profiling technology of a fluoro-phosphate optical moulded glass. The secondary profiling technology comprises following steps: step one, subjecting a raw materialto machine cutting and strip pulling, and thermally cutting the strips by a hot cutting technology to form blocks; step two, eliminating the edges and sharp apexes by a material rolling technology toform blocks with a ball like shape; step three, trimming the blocks when the weight of the blocks is close to the product weight; step four, softening the blocks by making the block rapidly go throughthe softening area of an evenly heated softening furnace; step five, hot-pressing and moulding the blocks in a die; and step six, carrying out an annealing treatment until the thermal stress of the optical glass is eliminated or the thermal stress is lower than an allowable value. Compared with the prior art, solved are the technical problems that the secondary moulding and processing of fluoro-phosphate optical moulded glass are hard to perform, the wear of the rolling materials is quick, the modification of edges and corners is not obvious, the edges and corners of angles are sharp, the surface of blocks are wrinkled, the ball and column are broken, and the glass is broken, and the yield is greatly improved.
Description
technical field [0001] The invention relates to the field of optical glass, in particular to a secondary molding process of fluorophosphate optical shaping glass. Background technique [0002] Compared with traditional optical glass, fluorophosphate optical molding glass has a very high technical content, and the secondary molding process is complicated. At present, there are many technical difficulties in the molding process that have not been broken through, resulting in a very low pass rate, which cannot be mass-produced and cannot meet the market. This is an unresolved technical problem in the art. With the rapid development of optoelectronic products, the demand for high-quality optical glass such as fluorophosphate is increasing. It is necessary to ensure that H-ZPK5 fluorophosphate optical glass products meet the requirements of the drawings for secondary pressing products, and improve the utilization rate of product materials. The technical difficulties that need t...
